Its sometimes its more like "shoot the guy with no lag this time and maybe cant dodge so well".
Not seperating yourself with Aces though, is indeed a good idea.
Ive seen several pilots trying to take on guys in a 1on1.
If the numbers are already uneven due to losses on your side, DONT DO it.
Youll get shot by the guy you are taking on and if someone of the other enemies is paying attention, he will rush to you as well, to make it a 2on1.
Can be an easy kill then.
Merge the battle, keep your mates informed that youa re under preassure.
If possible, someone tries to annoy one of your pursuers.
